As loneninja said if you're building a new system then there are far better performing chips available at a lower price than the C2Q's. The AMD Phenom II or Athlon II chips are a good example. As long as you have a solid CPU, the graphics card will be the more determining factor in your gaming performance.Post back and let us know and we can go from there.
The Intel G31 is a chipset not an actual motherboard model. It says on the website they support C2Q processors but to be certain which ones you will have to check on the supported CPUs list on the manufacturers website.
Stay away from Q8200 it is really quite slow and can't overclock Q9550 Is one of the best you can put on that board but can be very expensive expect to be around $200 for it. My suggestion is a Q9400 and overclock it or get an E8200 and overclock it, it will go up to 3.6ghz with lil trouble and will give you great gaming only a handful of games actually use more then 2 cores.
It would be very helpful if you provide us with a budget that you have.
If you planning on buying more memory too I would just rebuild with amd. You can get the Athlon II x4 630, and a Decent Asus Mobo for what you would pay for the comparable core 2 q9550. Plus you can buy ddr3 memory at the same price as ddr2 nowadays. This would give you better upgrade options down the road.

for the price of your upgrade 4Gb ddr2 + 775 socket CPU will cost alomost the same as a nice AMD combo (CPU+DDR3+MB).
for the price of the CPU upgrade only you can get a AMD cpu+mb combo.
That was the direction that I was about to take. When your buying several major components it makes better sense to go with the AMD route than upgrade an old 775 socket system.
